Porcelain water-closet bowl

GEORGE R. MOORE, OF PHILADELPHIA, PENNSYLVANIA.

PORCELAIN WATER-CLOSET BOWL.

SPECIFICATION forming part of Letters Patent No. 248,195, dated October 11, 1881.

Application filed March 22, 1879.

To all whom it may concern Be it known that I, GEO. R. MOORE, of the city and county of Philadelphia, in the State of Pennsylvania, have invented new and useful Improvements in Porcelain Water and Air Closet Bowls, which improvements are fully set forth in the following specification, reference being had to the accompanying drawings. The object of my invention is to provide an lmproved shape for water and air closet bowls, a shape that is better adapted to the specific use-for which the bowl is designed than has heretofore been made. The general shape for the top and body of my improved bowl is oblong or oval, with sides nearly vertical all around, though of less depth in front, as will be seen, and having the inside space at the bottom of it divided into back and front portions. The front portion, in the form of a slop- 1ng bottom highest at the front, extends nearly half-way from front to back. The rest of the bottom space is left entirely open. The top of the bowl is made with a wide rim, (the wider the better,) and a portion of it shelves over inwardly to keep the water used under force [or awash within desired bounds, safe fro m splashing over. There is also, a little below this top rim, an external flange for supporting the bowl upon other structures. There is what is called a fan, with suitable water-ways, (shown by arrows,) made inside the bowl just below the flange. The outside of the bowl has besides the top flange a lower one around it to adapt it to be joined to any structure upon which it may he used, generally on what is commonly called the trunk, an enlarged portion of a soil-pipe in water-closets, and in air-closets it is located above a vessel or pail. Between the two flanges is a hollow arm with passage to the fan for watersupply lor wash from reservoir.

Figure 1 is a perspective view; Fig. 2, a vertical transverse section.

A represents vertical sides; 13, sloping front the bowl left entirely open; D, the top rim.

F is a flange for supporting the bowl upon other structures; E, the fan connecting with the hollow arm. (Seen upon the outside of the bowl.)

The advantages of this shape are: It is less exposed to become soiled in legitimate use, its peculiar shape afl'ording a chute for urine from the front; it admits of having the opening through the bowl at the back part reduced to its smallest allowance consistent with cleanliness, so that when water fails, and in places where water cannot easily be obtained this bowl can he used with comparative decency. Another advantage arising from its shape: the quantity of air becoming contaminated by eX- creta in passing through the bowl is less than in ordinary cases in other bowlsin consequence of its vertical sides and oval form, and thus reduced space.

It will be seen that the outlet-aperture through bowl is not round, but is bounded in front by a straight. line, and is back of that limited only by the walls of the bowl.

I claim A porcelain water or air closet bowl with its lower part of oval or oblong shape and nearly vertical walls, and having its outletaperture bounded by a straight line across, or nearly across, the bottom portion of the whole how], by which the said outlet-aperture is substantially one portion of the bottom of the oval bowl bisected at its shorte t line, substantially as and for the purpose herein set forth.
